Overview
® LY1152 Rev.
1.
2 Inverting DC/DC Controller (SOP) GENERAL DESCRIPTION The LY1152 is a high performance inverting DC/DC controller, and the LY1152 designed to drive an external power switch to generate adjustable negative voltages.
Output voltage can be scaled to -40V.
The LY1152 quiescent current is about 90.
0uA and shutdown mode current can be reduced to 0.
1uA.
In the LCD bias contrast application, efficiency of 80% can be achieved with low cost PNP bipolar transistor drivers.
The LY1152 switching frequency can be around 60KHz to 160KHz range, and small size package is ideally suited for powered portable equipments.
